Hyundai Hit by Labor Dispute

SEOUL—A row between Hyundai Motor Co. and its labor union over weekend pay is causing major production disruptions at South Korea's largest auto maker, costing it some $732 million in lost revenue.

Plant workers belonging to Hyundai's 45,000 member-strong labor union have refused to work over the last six weekends following the implementation of a new shift arrangement that resulted in lower wages for weekend work.
